On
August 5, 2022, EPA received a report from the National Response Center (NRC)
regarding an incident at the Star Valley Trailer Court, north of Grover,
Wyoming. The NRC report stated an individual who lives at the trailer court
deliberately injected an unknown oily substance into the drinking water
distribution system. The trailer court
gets its drinking water from an artesian groundwater well and has approximately
32 connections, serving a population of roughly 72 persons. The well was not contaminated but six homes
are known to have been impacted. The
drinking water owner/operator shut down the system, notified all residents and quickly
installed two valves to isolate the contaminated homes.
EPA
has primary authority to enforce the public water supply protection program in
Wyoming and issued the system operator an order detailing the steps required to
bring the system back online. EPA dispatched an emergency response team to
assist the system operator with flushing the distribution system and taking
water samples.
